Tobacco pipe



Patented Oct. 29, 1929 THOMAS W; BIGONEY, OF PHILADELPHIA, PENNSYLVANIA j TOBACCO Pirn Appueation med June 5, 192s. Serial No. 282,979.

This invention relates to tobacco pipes, and the main object is to prevent the pipe'from acquiring objectionable characteristics such as rank odor and bitter taste. The cause 'for such objectionable` characteristics is that the moisture from the lburning tobacco as it is drawn through the pipe in smoking, tends to condense in thefsmoke passage in the stem of the pipe. Due to the porosity ot material,

such as briar root from which the stummel is generally formed, absorption of liquid mixture takes place, and if the pipe is kept frequently in use it is only a coi'nparatively short timeV bei'ore'the stem portion of the stummel becomes saturated and thus oliensive. As a result lof this condition some pipe smokers periodically send their pipes to a .so-called pipe hospital. to be skillfully cleaned and dried out. Gthers employ a series of pipes which are used on successive days,

so that each pipe has an opportunity of drying out for several days between successive periods of use. l/Vith this latter procedure the .saturation points is liever reachedand the development ot the objectionable characistics is prevented. j

In my improved pipe I avoid thev necessity ot' changing pipes or having the pipe cleaned and dried out, by providing the'pipe with detachable and interchangeable sections forming acore for the stem portion of the stummel where` the main condensation `and absorption take place. The special advantage ot this is that only one bowl and mouthpiece need be provided, and the plurality of interchangeable shank sections which also constitute cores for the stem portion of thestummel, may be used one'day each insuccession,

so that each of such sections may have several days to dry out between successive periods oi' use. 'Y

As a further advantage these sections when detached will dry out much more rapidly than bowl. y

In the accompanying drawings I have illustrated one embodiment ofiny invention and certain preferred details kot construction,

, but it 'Willrbe understood that various changes does a shank or stem which is integral with a opposite end has a recess preferably of the 7" may be made within the scope of my invention and the main object still be secured.

In these drawings:

Fig. 1 is acentral longitudinal section through my improved pipe,

Fig. 2 is a perspective view of one o1 the interchangeable shank sections,

Figs. 3 and 4Li are end views of opposite ends of the sections shown in Fig. 2, Y

. Fig. 5 is an end view of the stummel,y and 60 Fig. 6 is a side elevation of several of the interchangeable sections connected together to provide a longer stem if desired.

In the construction illustrated the stummel includes a bowl 10 with a comparatively G5 short hollow shank or stem portion 1l formed l integral therewith. This ystummel is preferably of briar root, asis also the interchangeable stem section 12. Thisy stein section 12 A has a tubular portion 13 surrounded by a re- 70v inforcing metal sleeve .14 which, together, fill the hollow in the' shank of the stummel with the end of the section 13 projecting slightly into the bowl cavity. The member 12 at the same diameter and length as thetubular por-l tion 13, so as to receive the end ot a mouthpiece 15. j

In carrying out my invention I make lthe interchangeable stem section 12 of porous so material such, for instance, as briar root, and I provide the stem portion .11 olthe stummel with a comparativelyflarge passage 16 extending all Of the way into the bowl. 'The tubular extension on the stein section 12 extends the full depth of the hole 16,1that is, into the base` of the bowl cavity. AItis or course understood that the mouthpiece and thel interchangeable stemfsectionv `12 have the usual smoke passage therethrough, which is of comparatively small diameter.

In my improved construction ythe smoke flows directly from the bowl into thesmoke passage of the section 12 without having comeV in contact with the stem portion of the stummel. Thus the condensation and resulting' vabsorption which takes place are solely in the stem section 12, and the mouthpiece, and primarily in the former. j.

Whenthe pipe has beenv smoked to such an '10U extent that the section 12 has absorbed a considerable portion of the moisture, it may be removed and replaced by a fresh section. As the section 12 extends all the way into the bowl cavity there will be comparatively no absorption by the wall of the stummel itself.

The tubular portion 13 of the stem section 12 being of comparatively small diameter, may rapidly dry when removed from the pipe.

The tubular portion 13 is preferably encased in the reinforcing metal sleeve 14 which may also extend out radially and form a ferrel around the end of the larger portion of the stem section. Thus a permanent lit is established between the removable stem and the stummel and there will be no liability of breakage of the parts.

The preferred manner of use is to employ one shank for one day and then to remove it and lay it aside to dry out. There may be any desired number of these shanks or stem sections consecutively numbered, for instance one for each day of the week, and each used for one day. It is also desirable. to leave the bowl detached during the night so that air may circulate freely through it. With reasonable attention to the procedure `above stated, it is impossible for my improved pipe to become foul.

Itis to be noted particularly that my improved pipe presents no inaccessible pockets in which the liquid condensate or mixture may collect, and no so-called saliva chambers, compartments, cartridge inserts or metal attachments wit-hin the smoke passage. The smoke flowing through the entire length of the pipe from bowl to mouth does not come in contact with any metal, and this'is particularly desirable as smoke drawn through or over metal rapidly produces a very objectionable condensate.-

Inmy improved construction no excessive condensation takes-place within the stem, and the portion of the stem which the smoke first enters, and where the absorption is greatest, is interchangeable and used for limited periods only.

lThe metal sleeve which is employed strengthens the tubular projection 13 and preserves a permanent fit within the hole 16, but this metal does not contact with the smoke and does not promote condensation. The invention does not constitute merely a det-achable or interchangeable stem or an additional insert of any kind, but includes the use of porous material surrounding the smokel passage of both the bowl and the shank, and the provision for the removal and interchange of the entire length' of the porous material V.which ordinarily becomes filthy as theresult of prolonged use. It involves a novel construction of the stummel and results in advantages which areV not obtained in any other pipe with which I am familiar.

There is, practically speaking, no addiration of the parts; that the complete pipe,

together with a set of interchangeable Shanks may be furnished for practically the cost of one pipe, and that it is necessary to break in onl one bowl. Furthermore the quality and avor of the` smoke drawn through a small hole in a briar root shank is decidedly superior to smoke drawn through or over a metal attachment or insert of any kind.

By means of my invention the line qualities of a simple old fashioned briar pipe are left intact, but the saturation evil is easily averted.

As the ordinary user would provide himself with Va plurality of these sections, two or more of them may be connected together in series, as shown in Fig. 6, to elongate the stem if desired. To permit of this the socket Y or recess in the outer end of the section l2 is made of the same diameter and depth as the cylindrical projection 13.

Having thus described my invention, what l claimA as new and desire to secure by Letters Pat-ent is:

1. A tobaccok pipe having a stummel including a bowl and a very short hollow stein section having an unusually large passage therethrough, a removable stem section and a projection integral therewith and extending through the hollow Vstem section of the stummel' into the bowl cavity, whereby the portion including the entire smoke passage from the bowl cavity to the mouthpiece iny able and interchangeable stem sections, each including :a projection adapted to extend through said passage into the bowl cavity and having a smoke passagetherethrough, and a separate mouthpiece adapted to be detaehably secured to any one of said interchangeable stem sections and having a smoke passage therethrough, whereby upon the absorption of moisture in one of the said interchangeable stem sections it may be exchanged for a similar but dry stem section.

3. A tobacco pipe having a stummel including a bowl and a very short integral hollow stem section with an unusually large passage therethrough, a mouthpiece, and an intermediate stem section having a body portion and a projection integral therewith at one end and extending through the stem section of the stummel into the bowl cavity, and means at the opposite end for attaching said mouthpiece, whereby the intermediate stem section containing the entire smoke passage from the bowl cavity to the mouthpiece is removable for drying, and whereby a free circulation of air for dryin the bottom of the bowl cavity is permitte when the intermediate stem` section is removed.

4f. A tobacco pipe having a stummel provided with a very short stem section having a thin wall and an unusually large passage therethrough, and a stem section of porous material having a body portion and a projection integral therewith and projecting through said passage into the bowl cavity,

whereby upon separation of the said stem sections rapid drying of the lower portion of the bowl cavity is permitted by free circulation of air through the stummel.

5. A tobacco pipe having a stummel provided with a very short stem section having an unusually large passage therethrough into the bowl cavity of the stummel and a removable stem section having a body portion and al projection integral therewith and projecting through said passage into said bowl cavity, said projection having a metal jacket thereon out of contact with the smoke passage, whereby upon separation of parts which have been subjected to the deleterious action of the burned tobacco said parts may rapidly dry out by reason of the greatly increased circulation o air in contact therewith allowed when said parts are separated.

6. A tobacco pipe including a stummel having a very short stem section with an unusually large passage therethrough into the bowl cavity, and a plurality of removable and interchangeable stern sections each including a projection containing a smoke channel and adapted to extend through said passage into the bowl cavity of said stummel,

whereby upon absorption of moisture in one of said interchangeable stem sections it may be replaced by a similar but dry section, and whereby rapid drying of the lower portion of the bowlcavity is facilitated by free access ot' air upon removal of said interchangeable stem section. j
